We're being asked to calculate the Kc for the following reaction:
6 CO2(g) ⇌ 6 CO(g) + 3 O2(g).
We're given the reaction: 2 CO(g) + O2(g) ⇌ 2 CO2(g) Kc = 2.23 × 1022
To calculate the Kc of the reaction equation, we’re going to use Hess’s Law. We’re going to manipulate the reactions with given Kc value to get the reaction equation with the unknown Kc.
At 1000 K, Kc = 2.23 × 1022 for the reaction: 2 CO(g) + O2(g) ⇌ 2 CO2(g)
What is Kc for the following reaction:
6 CO2(g) ⇌ 6 CO(g) + 3 O2(g)
A. 9.02 × 10–68
B. 1.11 × 1067
C. 4.48 × 10–23
D. 3.55 × 10–8
E. 2.81 × 107
